Texas Instruments TMAG6181-Q1 Angle Sensor

Texas Instruments TMAG6181-Q1 Angle Sensor is a high-precision sensor based on the Anisotropic Magneto Resistive (AMR) technology. This sensor with an integrated turns counter features two independent Hall sensors at the X and Y axes to track rotations. The TMAG6181-Q1 angle sensor also features a 20mT to 1T operating magnetic field that enables flexible mechanical placements and <2µs low latency outputs for high applications. This sensor supports differential- or single-ended applications. The TMAG6181-Q1 angle sensor is AEC-Q100 qualified for automotive applications.

The TMAG6181-Q1 angle sensor operates from 2.7V to 5.5V voltage range and -40°C to 150°C ambient temperature range. This sensor is available in 3mm x 4.90mm dimensions. The TMAG6181-Q1 sensor is used in E-bikes and 2-wheelers, encoder position sensing, servo drive position sensors, EPS motor position sensing, EPS handwheel angle sensing, and integrated belt starter generators.
